Application filed lletober 1, 1-923. 'Serial No. 665,788.

This invention relates to machines of the general type disclosed andclaimed in Letters Patent No. 1,289,729, issued December 31, 1918, toHarrison 8. Gripe. The machine shown in said patent is designed for thepurpose of applying paper or other covering material to the tops andbottoms of boxes whose sides and ends have previously been provided witha covering of similar material.

The present invention has for its object to generally improve thecovering applying and pressing devices of a machine of this type, andmore particularly to provide means for smoothing down any rough portionsat the corners of the box due to the imperfect application of the sideand endcovering, so as to cause the top andbottom covering to beperfectly smooth and fiat at these points; toprovide improved means forpressing the applied covering smoothly upon the box top or bottom, whichpressing means is. of such a character as to permit the same I to adaptitself readily to inequalities in the work operated on; and to provideimproved means for controlling the operation of said pressing. means soas to cause the same to engage the work at the proper time, saidcontrolling means being adjustable to adapt the same to boxes ofdifferent sizes.

,The foregoing and other objects of the invention, together with meanswhereby the same may be carried into effect, will best be understoodfrom the following description of one form or embodiment thereofillustrated inthe accompanying drawings. l t willbe understood, however,that the vparticular construction described and shown has been chosenfor illustrative purposes merely, and that the invention, as defined bythe claims hereunto appended, may be otherwise practised withoutdeparture from the spirit and scope thereof.

In said drawings:

simplified side elevation of the machine with the adjacent side of theframe removed and certain of the parts, not} essential to the inventionherein claimed, omitted.

Except as hereinafter described, the machine herein shown, as to itsgeneral organ-i zation and the parts not illustrated, may, if desired,be substantially-as more fully shown and described in Letters Patent No.1,289,- 729, above referred-to. 3 Said machine comprises a frame 25provided with longitudinal ways in which is mounted ;for movementtransverse to the covering applying and pressing devices, hereinafterdescribed, the carriage 26 of a work support 27 having ahead 28 forsupporting thebox b to be covered. The upper part of the head '28preferably comprises a board 4 detachably secured to said head, wherebyboards of different sizes may be provided for diiferent sizes of boxesto be covered. The carriage QT is reci-procated in its ways by mechanismwhich may be substantially similar to that shown in the Gripe patentabove referred to, but which is herein shown as of the type disclosedand claimed in another application, filed Qetoher 1, 1923, Serial No.665,789. For the purpose of the present case, "this mechanism may bedescribed as follows: The'carria'ge :26 is formed at its under side withears 30'co1rnected by links 81 with levers 3:2 suitably iulcrumed, as at33, to the frame 25. Dieposed between the lovers 32 is a lever :34fulcrumed at 35 to a bracket 36 secured to said frame. The levers 32 and34 are formed with longitudinal slots to receive slides 37 pivot-allyconnected, as at 38 and longitudinally adjustable in said *slots bymeans of mechanism generally indioated at 89 to adjust the operativeconnection of -the levers 32 and-34; and thereby vary the length ofthe-stroke of the carriage 26; The lever 34 is operated by a link 40having acam roller 4-1 which cooperates with a "cam 42 on a camshaft 43journalled in the frame 25, said link having a-f'orked endlembra'c- 251;j f' m ager;

This turningmovement is yieldingly resisted by the spring 80 acting through thetension frame 86, the tension of the spring being increased by thedownward movement of the arms 63. The smoothing roller 8 is also pressedagainst the work by the spring 82 which yieldingly resists upwardmovement of said roller in the slots 80. Said roller 8 is thereforeyieldingly pressed against the work as it is moved outwardly there'overby the turning of the heads 76, thus flattening down the portions 730and 480 of the-cover-- ing material making a edge of the box. Themaximum tension em erted by the spring 89 through the tension frame 86upon theheads '76, as well as the normal position of the parts, isdetermined by the adjustment of the nut 95.

In accordance with the present invention, the pressing member 52comprises a roller, pit 'efera bly provided with a rubberor peripheralsurface, said roller being journalled at its ends in studs 1-00slid-ably mounted in the-ends of arms T0 1 hale-ruined on the rodandoonnected by 'a cross anemher 102 to form a pressing frame. Withinthe ends of the arms 101 are springs 103 acting-to press the studs 100outwardly and yield-ingly resisttheir inward movement, tilt-re movementsof said studs being limited by lugs 104 secured, as by screws 105, to"said arms and extending through openings there- M1 into engagement withgrooves formed as the studs. By means of this construction theroller 52is pressed yieldingly against the work, thereby providing for an sureupon boxes of difierent quality and even pres compensating forvariations in the thickness of the boards 4.

The arms 101 are operated through links 106 bylevers in the form of arms1 07 "on a rock shaft 108 journalled in the framep25, said rock shafthavinganvarm 1-09 to which is-connected a link 11 0 supported by a link111 from the shaft 58 and carrying a cam roll 6 cooperating with a cam113 on the shaft 43. One of the lever"a1"-'rns 107 is connected by alink liw-itli alever 15 f' u'lorurrred -a-t1 6 on the frame 25 andformed with a bearing surface 17 which is engagedby aroller 18 on abracket 19 mounted in longi tudinal ways 20 on the underside of thecarriage 26' and adjustable in said ways longit-ud-ina lly of saidcarriage by means of adjusting screw 21 connectmg said oarneat fioint atthis,

i on the bracket.

The arms I01 and pressingroller 52 are raised through the connectipnsdescribed by the cam 113, which is formed with a low portion 123adapted, as the carriage 26 starts to move forwardly or towa rd the leftin Fig; 1 to release .the roller 6 and place the arms 1 01 and roller5-2 under the influ once-of gravity. Said armsa nd roller, however, areat this time held elevated by engagemen't of the roller :18 with thebearing surface 1 7 of the lever 15 which acts through the link '14,lever 10?, and link 106 to support said-parts until the carriage 26. inits "traversing movement, carries the. roller 18 out of engagement withsaid bearing surface '17, thereby releasing "the pressing roller andpermitting "the same to engage the work. The exact time of engagement ofthe roller 52' with the work may, therefore, be accurately determined byadjustment of the bracket 19, thereby adapting the machine for accurateoperation upon boxes of different sizes and shapes.
